California recorded its second-lowest Sierra Nevada snowpack on record this spring. That's not just a bad ski season, it's a water supply crisis. Snowpack is where California's water comes from. And when it doesn't materialize, agriculture, hydropower, and fire suppression all feel the strain.

Dacia Leon, CEO and co-founder of Supercool Earth, is building a company around a deceptively simple idea: use biology to make it rain and snow where it's needed most, on demand. Her company's core technology involves engineering microbes to produce high quantities of this pure protein cheaply, which is then used in snowmaking machines and for cloud seeding.

Supercool Earth is targeting high-margin markets first, starting with a snow-making additive for ski resorts. It’s a cheaper, greener, and scalable alternative to existing products like Snomax largely because it’s made of pure, biodegradable protein (no bacterial cells), has no smell, and is stable at room temperature.  The company is intentionally using natural proteins instead of non-degrading silver iodide used in traditional cloud seeding to streamline the regulatory process through EPA TSCA, which is faster than dealing with GMO regulations.

In this episode, Lara Pierpoint talks with Dacia about the science and commercial strategy behind Supercool Earth, the lessons she's carrying from Bio 1.0 failures, the public perception challenges around geoengineering, and what she'd do if $100 million landed in the company's bank account tomorrow.
